The solution to the high oil temperature of small punch press

If the temperature of the hydraulic system of the small press is too high, it is easy to cause the failure of the small press, and even the damage and shutdown will affect our production and processing tasks.

Let‘s take a look at the reasons for the high temperature of hydraulic oil in small punch presses.

1. The reason why the oil temperature of the hydraulic system of the small punch press is too high:

We can know from the principle of the hydraulic system of the small punch press that there are two parts that generate heat in the hydraulic system:

One is a power element oil pump that converts mechanical energy into pressure energy

The other is the control element and fulfillment element that converts pressure energy into mechanical energy;

These two parts will generate heat under normal operating conditions, and these heats are cooled by the cooling system of the system.

Because under this pressure, the influence of the pressure factor on the viscosity of the hydraulic oil can be ignored, and the influence of temperature on the viscosity should be considered first;

When the temperature increases, the cohesion of oil molecules decreases, and its viscosity decreases.

2. The composition and basic working principle of the hydraulic system of the small punch press

A complete small press hydraulic system should consist of these components: power components, execution components, control components, auxiliary components and hydraulic oil;

The effect of the power element (the oil pump in the system) is to convert the mechanical energy of the motor into the pressure energy of the liquid to power the entire hydraulic system.

Therefore, when one or several of these components do not work properly, the oil temperature of the system will rise.

3. Accelerate the aging of hydraulic oil for small punch presses

The oxidation reaction of the hydraulic oil of the small punch press is the main reason for its aging, and the occurrence of the oxidation reaction is closely related to the oil temperature.

Experiments have shown that when the oil temperature reaches the temperature zone (60°C), the oxidation reaction of the hydraulic oil will double for every 10°C increase in the oil temperature, and its life will be shortened by 50%.

.

After solving the problem that the oil temperature of the small punch is too high, we can debug it according to the parameters such as the model, do a good job in the treatment of the oil temperature, and debug to the appropriate oil temperature, which can also promote the efficiency of the production line.
